Close encounter with Rhea

Near its closest approach to Rhea on January 11, 2011, Cassini snapped a pair of images with both cameras. The left image is with the narrow-angle camera, which has ten times the spatial resolution but only one-tenth the field of view of the wide-angle camera. The two cameras have the same boresight, so the narrow-angle camera image occupies the center 10% of the wide-angle frame on the right, covering the middle of a large crater that Cassini is viewing obliquely.
